The screw batcher

The screw batcher



The automatic batcher for free-flowing naterials SWEDA DWS-301-50-3 (a screw batcher) is intended for batching of bad-flowing and dusting materials (cement, building mixtures, powders, mineral substances, flour, mixed fodders) in sewing bags (bags of the open type).

The operation of the batcher is based on cyclic batching of the material in the open (sewing) bag fixed by a pneumoclamp. Material batching is carried out by a screw conveyor. Material feed in the mode "ROUGH" and "PRECISE" is ensured by change of the rotational speed of the screw. After the batching end the bag clamp is unclenched and the filled bag is dropped automatically. At batching of the free-formative materials the installation of free-formative vibrators on the supply hopper is possible. On the board of the weight processor of the batcher the weight of the dose and the amount of doses (material) in pieces or tons is displayed by the accruing total.

о Advantages:

- Easy mounting and installation under the storage hopper;

- A semi-automatic mode of operation (the operator only hangs a bag);

- Non-volatile memory for storage of the journal of totals and settings;

- Link with the PC for account and registration;

- Bilingual (Russian/ English) interface of the user;

- The detailed documentation for mounting and maintenance.

Ample opportunities:

- High accuracy ±0,5%;

- Adjusting dose setting - from 10 to 50 kg;

- High capacity (from 100 bags/hours);

- Automatic adjustment of the settings "rough-precise" of batching;

- Execution of the construction from stainless steel is possible.

High reliability:

- A simple construction;

- Applicaton of the electronic components and the electronic drive of the leading foreign manufacturers.

On the display of the weight processor of the weight batcher the series of parameters of it's operation can be displayed on the operator choice: the value of the batching mass of the product, the amount of doses, the accruing total for a shift and a season etc.

The weight batcher for bad-flowing and dusting materials SWEDA DWS-301-50-3 with the bag sewing line SWEDA LZM can be used as a part of the packing complex.

Having filled and having coordinated the corresponding questionnaire with the experts of the firm, You can buy the weight batcher SWEDA DWS-301-50-3, meeting all Your requirements. If necessary we can mount and start up the batcher in operation at Your enterprise.

  • principle of the product weighing tensometric-electronic, the control mode-electropneumatic;
  • filling-up of the bag with the material - by flow of the falling material;
  • control of the batching process - automatic;
  • the batching process is accompained by the indication on the digital board of mass of the batching material and the total of doses by the accruing total;
  • the batcher has an out on the exteal recording devices by the standard interface RS-485;
  • bag hanging is made manually by the operator;
  • bag dropping is executed automatically;
  • for batcher embedding in systems of the information gathering the weight processor PV-310 ensures data transmission to peripherls (a PC or a portable board);
  • PW-310 ensures forming of the data joual for saving of the information about the common total, and also date and time of recording of this information in the joual and the joual of events for saving of the information on the executed processes by the maintenance personnel, and also recording of all errors;
  • saving of totals and settings of the batcher at s n cutting off the supply voltage is ensured;
  • PW-310 of the batcher has the selective (Russian/ English) interface of the user, firmware system of tests, password protrection of settings from casual or deliberate measuring, blocking of the batcher operation at corruption of setting data, convenient simple system of calibration of the weight-measuring device.
